Losing Connection to MAX Transit Mini

Hi,
I have a Windows-based tablet connected to a MAX Transit Mini. The router uses a FirstNet SIM and connects fine. It is providing my tablet a valid DHCP address (192.168.44.X) and the tablet has a good internet connection.
We just started using some new software on the laptop that calls the router’s API every 5 minutes to retrieve and send out the following health data. The API call being used is shown in parenthesis:

  • Lat/Lon location (/info.location)

  • Firmware version (/info.firmware)

  • Cellular information and signal strength (/status.wan.connection)

    After running for about 1 day, I find the tablet offline with an invalid IP address (169.x.x.x). If I restart the tablet, it still doesn’t get an IP address. If I restart the router, the tablet immediately gets a good 192.168.44.x address and returns to obtaining and broadcasting the health data. This tells me I have an issue with the router.
    Could the API calls be causing the disconnections to the router? Are there settings I could change to help with this issue?
